Eight species of the subgenus Pachydinodes were reported from Palaearctic region (Kirschenhofer, 2003), among them four species, Chlaenius (Pachydinodes) abstersus Bates, C. (P.) pictus Chaudoir, C. (P.) tetragonoderus Chaudoir, C. (P.) virgulifer Chaudoir were reported in Korea up to now (The Entomological Society of Korea and Korean Society of Applied Entomology, 1994; Park and Paik, 2001). Members of this subgenus are characterized and easily distinguished by external morphology, like shapes of elytral spot or bend at apex and colorful diversity at head and pronotum dorsally. These species have well developed hind wing and tarsal claws which can be able to live on the tree flying and catching and feeding the small worms etc. (Nakane, 1986).

Notes. This species identified easily by greenish head and pronotm in dorsal and shape of yellowish bend at elytral apex (Nakane, 1986). And it is very similar to C. virgulifer, but distinguished by size, dorsal color and elytral bend shape.

This study was supported by the project of the survey of Korean indigenous species of the National Institute of Biology Resources (NIBR) under the Ministry of Environment, Korea. The photography system (Nikon SMZ-U, Japan) for this research was supported by Kyungpook National University Research Fund, 2012.
